I've been wanting a wide angle for a while and after a lot of pondering I got the EF-S 10-22mm. It stuck in my throat a little that for the same price I could have had the EF 17-40mm f/4L but 17mm really wasn't as wide as I was looking for. Although this was taken at 10mm it's been cropped a bit. Very pleased with it so far but I've only had it a couple of days...
